Hello I play with the idea to buy me a roadster and have stuck with a SLK or Z4 . Since I am not really an expert I want to ask you once . My budget is at a maximum of 20 000 Euro How does it look with the two candidates in terms of reliability and running costs . I actually like both of the looks . Maybe I also missed other brands and vehicles and you tell me I should definitely look at this or that . Definitely looking forward to any answer . See you then
